Annealed ASTM B541 vs. Annealed S45500 Stainless Steel

Annealed ASTM B541 belongs to the otherwise unclassified metals classification, while annealed S45500 stainless steel belongs to the iron alloys. There are 21 material properties with values for both materials. Properties with values for just one material (12, in this case) are not shown. Please note that the two materials have significantly dissimilar densities. This means that additional care is required when interpreting the data, because some material properties are based on units of mass, while others are based on units of area or volume.

For each property being compared, the top bar is annealed ASTM B541 and the bottom bar is annealed S45500 stainless steel.
